💡 𝗝𝗔𝟰 𝗙𝗶𝗻𝗴𝗲𝗿𝗽𝗿𝗶𝗻𝘁𝗶𝗻𝗴: 𝗕𝗲𝘁𝘁𝗲𝗿 𝗩𝗶𝘀𝗶𝗯𝗶𝗹𝗶𝘁𝘆 𝗶𝗻 𝗘𝗻𝗰𝗿𝘆𝗽𝘁𝗲𝗱 𝗧𝗿𝗮𝗳𝗳𝗶𝗰 In environments where most traffic is encrypted, traditional indicators stop giving you the visibility you need. That’s where JA4 fingerprinting changes the game. Instead of relying on previous TLS-only hashes like JA3, JA4 introduces a modular format that spans TLS, HTTP, SSH, and more while staying human-readable. Because each segment of the JA4 format describes a different behavioral component, you get a structured way to compare clients, spot deviations, and understand why a connection stands out. If a single segment doesn’t align with your baseline, that anomaly becomes an immediate investigation pivot. This makes encrypted traffic analysis far more actionable. You can spot non-browser cipher suites, unusual cookie behavior, suspicious client patterns, or automated tooling hiding inside otherwise normal TLS sessions. JA4 strengthens detection logic, accelerates investigations, and helps analysts map attacker behavior with meaningful context. 👉 Read more about JA4 fingerprinting: https://lnkd.in/ey4dHwqF #CyberSecurity #ThreatHunting #JA4

Hunt’s Active C2 Servers dashboard lets analysts monitor C2 families over time, see spikes in activity, and identify the infrastructure that has recently come online. When new C2 nodes spin up, you see them immediately. No waiting. No third-party dependencies. Recent C2 discoveries, hosting details, and timestamps are visible at a glance, so you don’t just know who is out there but when they appear, what their IP addresses are, or even search for specific malware families. If you need real situational awareness, start here. 👉 Start monitoring live C2 activity today: https://lnkd.in/dgV24xxN #CobaltStrike #ThreatIntel #MalwareOps #CyberDefense

🇨🇳 China-Linked APT31 Launches Stealthy Cyberattacks on Russian IT Using Cloud Services The state-affiliated group APT31 (also known as Altaïr, Judgement Panda) has targeted Russian IT service providers and government-adjacent contractors between 2024-25, using trusted cloud platforms like Yandex Cloud and Microsoft OneDrive for C2 and data exfiltration. Their tradecraft includes spear-phishing with LNK files, long-term stealth (some intrusions since 2022), use of living-off-the-land tools (SharpChrome, SharpDir), and persistence via scheduled tasks masquerading as legitimate apps. https://lnkd.in/eUc3A3Be #CyberSecurity #ThreatHunting #APT #CloudSecurity

🌐 AdaptixC2 Uncovered: Capabilities, Tactics & Hunting Strategies Two months ago, we did a deep-dive to explore the lightweight yet full-featured command-and-control framework AdaptixC2. The research reveals how a modular, open-source C2 tool is being used in real operations with 102+ active servers across multiple countries, blending into cloud infrastructure just like any legitimate service. The research walks through how AdaptixC2 leverages HTTP, TCP and SMB channels, runtime API resolution and custom hashing to stay stealthy, while still offering operators extensive capabilities for system control, persistence, file operations, and lateral movement. Even with its flexibility and modular BOF design, our team uncovered reliable signs defenders can use, such as repeated TLS certificate reuse, default ports like 4321, and the recognizable “Server: AdaptixC2” header.

📌 𝗔𝘁𝘁𝗮𝗰𝗸𝗖𝗮𝗽𝘁𝘂𝗿𝗲™ 𝗔𝗣𝗜: 𝗙𝗶𝗻𝗱 𝗥𝗲𝗮𝗹 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 𝗙𝗮𝘀𝘁𝗲𝗿, 𝗪𝗶𝘁𝗵 𝗙𝗶𝗹𝘁𝗲𝗿𝘀 𝗧𝗵𝗮𝘁 𝗔𝗰𝘁𝘂𝗮𝗹𝗹𝘆 𝗠𝗮𝘁𝘁𝗲𝗿 Attackers leave behind far more than hints. They expose malware, phishing kits, C2 dashboards, staging servers, and entire attack chains inside open directories that often sit untouched. AttackCapture™ turns that exposure into an actionable dataset you can filter and investigate in seconds. The API gives you a direct view of adversary infrastructure along with filenames, content types, tags, MITRE techniques, timestamps, GitHub references, enrichment layers, and confidence scoring. You can query by malware names, ports, host providers, tags, or any indicator that matters to your investigation. Whether you track actors, hunt live threat activity, or need reliable enrichment for internal tooling, AttackCapture™ lets you surface exactly what is exposed right now and decide what to escalate next. https://lnkd.in/eRYWZnwT #ThreatHunting #ThreatIntelligence #MalwareResearch #CyberSecurity

⚠️ Samsung Zero-Click Flaw Exploited for In-The-Wild Surveillance A zero-click vulnerability in Samsung’s messaging/processing stack is being abused in targeted surveillance campaigns to install implants without user interaction, bypassing usual phishing vectors. Look for abnormal binder transactions, unexpected native processes spawned by system apps, sudden battery/network spikes, and unusual DNS/HTTPS calls originating from handset services. https://lnkd.in/guGFYGkB #MobileSecurity #ZeroDay #AndroidSecurity #ThreatHunting

🚨 𝗩𝗲𝗻𝗼𝗺𝗥𝗔𝗧 𝗨𝗻𝗱𝗲𝗿 𝘁𝗵𝗲 𝗟𝗲𝗻𝘀 𝗼𝗳 𝗢𝗽𝗲𝗿𝗮𝘁𝗶𝗼𝗻 𝗘𝗻𝗱𝗴𝗮𝗺𝗲 The latest phase of Operation Endgame in November 2025 brought down more than 1,000 malware-hosting servers, including infrastructure linked to families like VenomRAT. This takedown gives helpful context for looking at how VenomRAT activity has shifted over the last few years. We have been tracking VenomRAT infrastructure for some time, and the data shows clear changes in how operators move. Servers rotate more often, targeting keeps expanding, and 2025 shows a noticeable decline that lines up with the increase in monitoring and coordinated takedowns.

💡 C2 Channels Are The Hidden Communication Backbone of Cyber Attacks These are far more than technical relics, they’re the real-time lifelines that let attackers issue commands, move laterally, and exfiltrate data once a host is compromised. Effective hunting of C2 channels involves profiling anomalous outbound traffic, identifying irregular beaconing intervals, and detecting reused or suspicious TLS certificates. Tools that map domains, IPs, and behavioral indicators can elevate a SOC from reactive to proactive defense.

🚩 Microsoft Fixes 63 Security Flaws, Including Windows Kernel Zero-Day Microsoft’s November 2025 Patch Tuesday update addresses 63 new vulnerabilities across its ecosystem, with four rated Critical and 59 Important. Among the fixes is a Windows Kernel race condition flaw, tracked as CVE‑2025‑62215, which has been actively exploited in the wild. This race condition vulnerability allows a low-privilege local attacker who has gained access to a machine to escalate privileges to SYSTEM. Exploitation requires winning the race condition in shared kernel resource handling, but successful proof-of-concepts were observed in real-world attacks. https://lnkd.in/e3i4b5-E #CyberSecurity #WindowsKernel #ZeroDay
